Title: Underwater structures with seal against water leakage - are sealed directly by slowly sinking porous and bonding material mixture
Inventor: MEMMEN JOHANN
IPC: E02D31/10
Filed: 1975-04-03
Abstract: The system is used for sealing of structures which are constantly exposed to water pressure. No diving is required on sealing of tunnels or bridges. Sheet piling can be sealed for carrying out subsequent concreting work without being disturbed by water. The sealing is carried out by scattering into water a slowly sinking porous material to which bonding material is added. This composite material is scattered near the surfaces to be treated. A tube is immersed into the water close to the wall to be treated and the sealing material is fed through a funnel into the tube. The above processes are combined and repeated a number of times. This method can also be used for repairing underwater damage.

Title: Encapsulating electric components with resin - using transparent mould in which resin is partly hardened by ultra-violet light before fully curing
Inventor: OTSUKI AKIRA
IPC: H01C1/028
Filed: 1976-02-03
Abstract: In applying a protective coating to an electric element, the novelty is that the element is placed in a mould which transmits ultraviolet light (UVL), leaving a space so a liq resin can be cast round the element. UVL is then used to harden at least the outer surface of the casting, so that the latter contg. the element could be removed from the mould without distortion, if required. The casting is then heated either in the mould or outside the mould to complete the hardening process, if the casting was left in the mould, for final hardening it is removed afterwards. The liq. resin pref. contains by wt. 10-70 pts. of >=1flame retardant per 100 pts. resin, the pref. retardant being aluminium hydroxide. The UVL is pref. used in an inert gas atmos, and a mould open at its top is pref. used, the liq. resin being covered by an inert fluid. The process is used e.g. to encapsulate capacitors resistors, etc. to prevent damage or corrosion thus increasing their working life. Provides a rapid moulding process using inexpensive moulds, and producing a glossy surface which is commercially attractive and crack-resistant.

Title: Separator for removing liq. droplets from gases - has liq. trapping slots with both overlapping and non-overlapping edges
Inventor: KALL HORST DIPL ING
IPC: B01D53/26
Filed: 1976-06-25
Abstract: An arrangement for sepg. liqs. from gases consists of >=2 separators in series with an agglomerator between them. The edges of the liq.-trapping slots in the upstream part of the first separator overlap, whilst those of the slots in the downstream part of the first and of those in the whole of the second separator do not overlap. The down-stream lips of at least some of the slots in both separators are joined to grooves. The separator is used to remove suspended droplets of liq. from gas streams. Slots with overlapping edges can be 'blocked' by individual liq. drops retained by surface tension in the slot mouth but have a high capacity to carry liq. away once trapped. Open mouthed slots can remove droplets but are more prone to allow re-entrainment of sepd. liq. Overlap slots are used where the liq. concn. is high and a film of liq. is formed on the separator surfaces, whilst open slots are used where the liq. concn. is low and in the form of single droplets. This gives high efficiency of sepn. for a range of drop sizes and concns.
